Unrecognized expense for DLH employees	(a)	$	5,982
Unrecognized expense for non-employee directors		324
Total unrecognized expense		$	6,306

Ref (a): The remaining compensation expense is recognized as the requisite service is rendered. The compensation expense for that portion of awards has been based on the grant-date fair value of those awards as calculated for recognition purposes under applicable guidance. For options that vest based on the Company's common stock achieving and maintaining defined market prices, the Company values the awards with a Monte Carlo binomial model that utilizes various probability factors and other criterion in establishing fair value of the grant. The related compensation expense is recognized over the derived service period determined in the valuation. On a weighted average basis, this expense is expected to be recognized within the next 4.39 years.

The aggregate intrinsic value in the table below represents the total pretax intrinsic value (i.e., the difference between the Company’s closing stock price on the last trading day of the period and the exercise price, times the number of shares) that would have been received by the option holders had all option holders exercised their in the money options on those dates. This amount will change based on the fair market value of the Company’s stock.
